I have a 2007 Accord. I’m having to replace the battery in it about once every two years (I’ve replaced it 3 times now in the past six years). Had it looked at, can’t figure out what’s draining it or why.

When I turn the car off, the indicator dings at me and the dashboard shows that my headlights are on even when I have the headlights turned off. I feel like these two things (battery and false indicator) must be related but can’t figure out how to fix it. Any advice?
